Vehicle Security Module
WARNING: This page is about a different car, the 2005 Lincoln Navigator and 2005 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle security module receives inputs from the following:
- Door ajar switches
- Keyless entry keypad
- Ignition switch
- Remote keyless entry (RKE) transmitter
The vehicle security module uses these inputs to control an output signal to the instrument cluster, which controls the battery saver relay and courtesy lamp relay output.
